Data confidence 70 medium

How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

The nature of electron-hole trapping centers in Na2SO4-Mn and K2SO4-Mnferroelectric crystals was studied by spectroscopic methods. It is shown that several types of impurity electron-hole trapping centers are created in such crystals under electrons and holes are localized at brokenlattice sites near the Mn2+ impurity.
